This invention aims to provide improvements in a separable fastener.

\ In the drawings, which illustrate a pre ferred embodiment of my invention 5 Figure 1 is a front elevation of the 'de-' vice; l

Fig. v is a section on the line 2-2 of Fig. 1 being partly in elevation; i Fig. 3 is a section similar to-Fig. 2, but showing the stud unlocked prior to disengag'ement from the socket; Fig. 4 is a rear elevation ofthe stud; Fig. 5 is a section 011 the line 5-5 of Fig.

Fig; 6 is a front elevation and side elevation, respectively, of the latch member. In. fasteners as previously constructed, great difficulty has been experiencedin co n: bining simplicity of construction, reliabtlity, and facility of operation. One wellknown' fastener presents a flush type socket for application't'o an automobile bodyfzt resilientstud for applicationto the curtain, a locking part carried the stud for lock5 ing the head of the stud in expanded position and a press button for moving the locking part out of its locking position. 'An-' other fastener is the same as that'just described, except that the locking part iscarried by the socket. In the present disclosure, I have elected to illustrate the latter type of locking part, though various features of my invention are new and useful irrespective-of the type of locking part used. Y

In the embodin'i'ent of my invention illus trated, tlieconstruction is simple, reliable and for many purposes can be operated with greater facility than is the case with fas-v teners presenting puslrbuttons, pull-knobs and other similar manipulatory unlocking devices.

Referring to the embodiment of the invention illustrated in the drawings, 1 have shown a flushty pe socket including a cas-" ing 1 presenting a stud-receiving aperture 2 and secured to'the body 3 of an automobile, or like support, by an attaching screw 1.1 thus far described, the socket is substantial- 1y as shown and described in the co pending application to Andrew S. Anderson, Serial No. 708,724, filed April 24th, 1924. 1

VVi thin the socket (Figs 2 and 3), I have provided a combined sealing and locking part 5 presenting a locking extension for cooperation with a stud. I prefer that this combined sealing and locking part shall, as

shown, present a tubular part .6 slidable, within the casing to provide a substantial bearing for the rest of the sealing part 5.. The outer end ofthe sealing part 5 isfirst pressed inwardly to form a depressed portion 7 and then outwardly to providea relatively long round-headed locking portion 8 for looking a. stud with the socket. The sealing'p'art is normally pressed into aperture-closing position by a spring 9,and -the v locking portion Sprotrudes into the stud- Th a s al ng and receiving aperture 2. lock ng part is providedin the socket which,

because of its rounded'head, is easily regis terablewith the headof a stud and'cannot tip relative tOithB casing because of the-long v ea ng u fa ag stth nsid o the a ing; t e by n uring p sitiv l cking means for locking a stud with the socket.

The s d, asil ustmt d, is SQCHYQQ w th u t l 01 aut l'neb l or th l e nd Pr s nts a s cktrengz e spar 11. hav n a plurality of longitudinal slots to provide a icq tra t l' W l'BlH Q LS b G l ea il2 f engagement with the stud-receiving aperwif 2 i t soqk tt lVhile thesocket-engaging part 11 may be secured to the curtain-10, in any suitable manner, I have securedit theretoby first securing a front plate 13 to thebase 14 of the socket-engagingpart 11 by a plurality of short prongs lo (Figs. 2, 3'and 5),Wl1iCl1 are clenched overthe periphery of the base lat anclon to theadjacent face thereof. The front plate 13- also "presents a plurality of long prongs l6'which pass through thecurtain 10 through slots ina back plate 17 1.0

cated "at the oppositefface of the CLllIZfllll and are then clenched inwardly against'the face of the back plate 17, as illustratedin Figs. 2 and 4. Thus the stud is secured to that side of the curtain opposite the side facingthe socket and presents a socket-err gaging part llwvhich passes through the curtainlO and the back plate-.17 and presents a contractible' and expansible head forlock: in}; engagementwith the socket. j

The locking portion 8 in the socket-engagestheinwardly bent portions 18 of the head of the stud to; prevent contraction thereof Thus the head'of the stud is locked with the socket :and 'can onlyibe separated therefrom pursuant to displacement or the lockingportion 8 from the headof' the stud. To this end I have provided-a shiftabl'e part, herein the lever 19 "pivoted between thebase 14 of the socket-engaging part 11 (Figs. 2, 3 and 5) and the front plate 13. The lever 19 is adapted to operate an unlocking part 19*- which, in this instance, is shown as being formed integral with and presented at one end of the lever'19. The unlocking portion 19 is located within the stud for engage ment with and operation of the locking portion 8. The lever 19 also presents a depending finger 20' extending toward the free edge of'the curtain and operable to move the lever about the pivot to move the unlockino portion 19? in such manner that it will displace the locking portion 8 from the head 12 of the stud. i

The front plate 13 is spaced away from the base 14 of the socket-engaging part'll by a pluralit of struts 21 extending outwardly from the base 14, thus providing a space between the front plate 13 and curtain 10 to rmit to and fromovement of the depend m finger 20. 7

The unlocking portion 19 of the lever 19 is relatively narrow at that end located at the head of the stud and gradually widens toward the point at which thelever is pivoted,

thus providing a relatively wide bearing for the pivot and for the depending finger 20. The lever 19 including the portions 19 and 20 may be considered broadly as releasing means.

Longitudinal movement of the lever rela- ,tive to its pivot is prevented by providing two slots 22, 22 at the edges of the lever adj acent the point where the lever bears on the pivot, which engage two of the struts 21 which space the front plate 13 relative to the base 14 of the socket-engaging part 11, as best illustrated in Fig. 5. 7

While the front plate 13 could be constructed to cover the depending finger of the lever, I prefer to leave a portlon of the finger 20 exposed below the edge of the front plate 13, so that the lever may be operated either by hand orpreferably by pulling upon the curtain, as hereinafter more fully described.

The stud and socket may be engaged by pressing upon the front plate 13, thereby 1 urging the head of the stud into the stud-receiving aperture 2 in the socket. As the head 12 contracts and enters the aperture, it engages the outer face of the locking portion 8 of the sealing part and, as the looking part cannot enter the head because of the contracted condition of the latter, the locking part is moved inwardly relative to the socket casing 1, against the pressure of the spring 9, until the head 12 of the stud passes through the aperture 2. The head then expands and engages back of the wall surrounding the aperture and-the spring 9 then urges the locking portion 8 into engage ment with the inwardly bent portions 18 of the head, thereby preventing contraction of the head or separation thereof from the socket by a strain on the curtain at three sides of the stud. The rounded head of the locking portion 8 also engages the end unlocking portion 19 of the lever 19 and urges it inwardly relative to the socket-engaging part 11, thus moving the depending finger part 20 of the lever 19 against the outer face of the curtain-10, asillustrated in Fig. 2.

The preferred mode of separating the stud from the socket is by grasping the lower flee edge of the curtain 10 and exerting a slight outward pull thereon, as illustrated in Fig. 3. Thus the curtain moves the depending finger 20 toward the frontplato 13, thereby tipping'the lever 19 about its pivot to urge the unlocking portion toward the locking portion 8 to move it out of on p gagement with the inwardly bent portions 18 and permit contraction of the head 12 of the stud. So far, there hasbeen no relative tipping movement of the parts of the stud relative to the socket except the lever. Further pull upon the curtain 10 tips the stud, from the position shown in Fig. 3, out of engagement with the socket.

The lever, operable by a pull on the curtain, thus constitutes a preferred form of means,.opera-ble by an initial movement of the curtain relative to the, rest of the stud, J

for moving the locking member out of engagement with the stud.

a The stud, as shown, is inexpensive and easy to assemble to a curtain inasmuch as the lever 19, front plate 13 and socket-engaging part 11 are assembled as a unit at the point'of manufacture.

VVhileI have shown and described preferred form of one embodiment of my invention, it will be understood that changes, involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from thescope of my invention, which is best defined in the following claims.
